Prior to the Conversion, FLG was not engaged in any significant operations and did not have any assets or liabilities. After the Conversion, which was completed on December 11, 2018, when FLG issued 3,530,150 shares at $10.00 per share for gross proceeds of $35.3 million, FLG’s primary assets are the outstanding capital stock of the Predecessor and a portion of the net proceeds of the Company’s IPO, which was completed on December 11, 2018.

Federal Life, a subsidiary of Federal Life Holding Company, completed a reorganization in 2016 in which it converted from a mutual to a stock insurance company within a newly created mutual holding company structure. As part of this reorganization, Federal Life Mutual Holding Company was formed as an Illinois mutual insurance holding company and Federal Life continued its existence as an Illinois stock life insurance company. All of the shares of Federal Life were issued to FEDHO, an intermediate holding company that, in turn, is a wholly-owned subsidiary of the Federal Life Holding Company. Federal Life has two wholly-owned non-insurance subsidiaries, Americana and FED Mutual Financial Services, Inc., discussed further below. Federal Life’s in force business is primarily comprised of traditional life policies (term insurance, whole life insurance, non-medical health insurance, and group life insurance), interest sensitive contracts, and fixed deferred annuity contracts. Federal Life primarily sells its interest sensitive life, whole life, term life, fixed and indexed annuities through a network of independent agents. Federal Life is licensed to sell new business in the District of Columbia and all states except Maine, Massachusetts, New Hampshire, New York and Vermont.
